Regarding proper settings there's a lot to do. Starts with identfying the internal behaviour of the SD card controller (page and erase block size) and then adjust partition and filesystem parameters to that. Then disabling ext4 journaling and switching to writeback helps a lot for specific use cases (but longsleep enabled the journal for a good reason: Since many Pine users simply have no clue what a filesystem is and that you should shutdown the Pine before powering off so that the filesystem is in a clean state after the next boot). And so you can tune other parameters as well (even exchanging the filesystem with for example btrfs with active transparent compression)
How do you get these informations?
